Study Rationale Adrenocortical carcinoma (ACC) is a very rare disease with a high risk of relapse after radical surgery. The efficacy of adjuvant mitotane treatment is suggested by a retrospective multicenter international study showing that postoperative mitotane treatment was associated with a significant reduction of the risk of relapse and death. However, these promising results need confirmation in a randomized prospective study. Caution should be adopted particularly in patients with low risk of disease relapse, in whom the benefit of therapy should be weighted against the side effects. Even if an adjuvant treatment seems justified in patients at high risk of relapse, a randomised prospective study is needed to assess whether such a treatment is efficacious in patients at low-intermediate risk.
The purpose of the present study is to determine whether adjuvant mitotane treatment is effective in prolonging the disease free survival in patients with adrenocortical carcinoma at low-intermediate risk of progression who underwent radical resection
Endpoints Primary : To compare DFS (Disease Free Survival), defined as the time between the date of randomization until documentation of any of the following failures (whichever occurs first): -local or distant recurrence of disease;-death from any cause or completion of follow-up.
To compare OS (Overall Survival), defined as the time interval between the date of randomization and the date of death from any cause or the last known alive date; To compare quality of life measured by EORTC-QLQ-C30 To compare toxicity, graded according to the NCI-CTG criteria; To compare DFS and OS in patients who achieve or not serum mitotane concentrations > 14 mg/L; To compare DFS and OS between the 2 arms in patients subgroups stratified according to: type of hormone secretion, stage of disease, histopathologic characteristics.
